Evaporating Black Holes And An Entropic Scale-Hierarchy
arXiv:gr-qc/9409023
Abstract
It is argued that a characteristic length may be associated with the entropic state of a spherically symmetric black hole in the cosmological context. This length is much smaller than the Schwarzschild-radius of a black hole and may act as a regulator of arbitrarily high frequencies apparently entering the usual derivation of Hawking's radiation.
